Paint formulations containing barium salts of hydroxy acids such as citric, tartaric, salicylic, alizarine, quinizarine, and chloranilic in their anhydrous or hydrated forms are useful as primer coats for inhibiting rust for time periods equival- entto or better than those primers containing oxides and salts of lead. Barium salt mixtures, coprecipitated blends and barium salt coated substrates are particularly useful as paint additives. |
